According to investigators, the subject and his wife were involved in a domestic dispute that escalated into a shooting.  When the subject started shooting, his wife told her mother to run out of the house and call for help. Once uniformed officers arrived, they entered the home and discovered the wife and their seven year old son deceased from apparent gunfire. The subject was found deceased from a self-inflicted gunshot wound.  Their eight year old daughter was also shot, but found alive.  Miami-Dade Fire Rescue responded to the scene and transported the young girl to Nicklaus Children's Hospital in critical condition.
